(KMOV.com) -- One of St. Louis’ must-see attractions is generating a lot of complaints about safety.

A News 4 viewer says he was near the Arch Grounds Saturday and that he, along with other tourists, were scared to see things get out of hand.

Police say residents can expect to see more officers near the Arch Grounds and the Riverfront, especially as school lets out for the summer.

Officers said on the Saturday night in question, they made a drug arrest on Leonor K. Sullivan Boulevard, then put up gates to impede traffic to ensure things wouldn’t get out of hand.

Officers say the strategy worked, and the gates are part of a new strategy adopted last summer. The gates are about a half mile apart on Leonor K. Sullivan and are typically used on Friday and Saturday nights.

Captain Kenneth Kegel says that as part of their safety approach, police are also deploying additional officers on weekends to keep an eye on the Riverfront area.

Kegel says one of the biggest complaints is loud music, and that’s going to be one of the things that officers will focus on this year.

Lumiere Place recently pledged $500,000 toward hot-spot policing.

Part of that money, police say, will go toward extra officers along the Riverfront.
